Hi Ovirt&KVM, Here is the details :- 1. Ovirt :- 3.4 2. VM :- Centos 6.5 3. VM Disk Partition :- Based on LVM 4. Base Datastorage :- Gluster
I am able to expend the disk...but the disk expand doesn't touch the partition table..so after expand all the existing partition remain with the same disk size....now i need to manually create another partition and add it in to Volgroup and resize the logical volume...
